Hi guys,

On Monday night I shut down my PC and went to bed - everything was fine during operation that evening yet when I wake up in the morning and attempt to boot it up, I get a series of beeps followed by nothing coming up on my monitor. The fans stay spinning/the power stays on, I can hear hard-drive chatter when the computer normally loads the windows logon screen. I can even type in my login password and hear the windows logon sound through my headphones but don't have anything on my display! So the computer is booting but there is something inbetween power on and windows actually loading thats failed overnight?

Given that the most glaring problem appears to be a display issue, I would assume logically that there is something wrong with my graphics card?

I don't know the beep pattern and I couldn't tell you exactly how many there are as they all seem to run together somewhat? It's definitely not one long continuous beep, more like a series of beeps that all make up one scary noise that lasts about 2-3 seconds during POST and doesn't repeat.

For the past month or so there has been the odd beep from the computer whilst in operation but as it didn't happen with any massive regularity or repeat itself for a period of time, I didn't think that much of it. I simply checked the cpu/gpu temperatures (which were both well within normal limits) and carried on.

So far I have tried the following;

- Reseating RAM & graphics card
- Trying to boot up using just one of my sticks of RAM
- Removed as much dust as possible from inside the case and checked connections (everything looks as normal?)
- Using a different plug socket
- Tried using a different monitor (tried my other DVI port also)

I am completely bamboozled now and I can only think a piece of hardware has fried but the problem is I can't identify with any certainty at all what it might be. My computer specs are as follows:

Intel Core2Duo e6600 @ 3.3ghz (voltages are at default)
EVGA nforce 680i SLi mobo
BFG Nvidia 8800GTX (comes overclocked as standard)
2GB Corsair Dominator PC6400 800mhz RAM
Raptor X 150GB Hard-Drive
Enermax 850w PSU
Creative X-fi Fatal1ty Sound-Card
Windows XP SP3

Any help would be greatly appreciated!

Sounds like the graphics card to me. Although if you have a second monitor (or another PC) it might be worth ruling that out first.

If the monitor is OK then I would replace the graphics card. Maybe buy the cheapest you can find (about 30 probably) or maybe borrow one to make sure that is the problem.

I recently moved country and I only know my brother here and his card is AGP not PCI-e.

I believe the monitor is ok as I've tried a 2nd samsung I had lying around and it still gave the same beep sequence and lack of boot.

It's bound to be the graphics card. If the machine sounds like it's running normally and you can hear the hard drive going when you log in that rules out memory, board or harddrive probs.

If it was me I'd feel sure enough to replace the GC.

That was my logic behind it mate. Thing is, the fan on the graphics card definitely spins up so its not completely dead. Is it common for cards to be knackered but still rotate its fans?

Not heard of that before but it doesn't seem inconceivable that the card is getting power from the PSU or board but one of the on card chips has failed.
